In the production of semicylindrical or cylindrical bearing liners, means are provided for supporting one or more liners in an electro-plating bath comprising a rigid cylinder and a flexible lining therein adapted to establish close contact with the outer surface of the liner or liners to provide an effective seal preventing contact of the electrolyte with the outer surface. In the construction shown, the liners 3 are contained on a carrier comprising a double-walled tube, the outer wall of which is a rigid cylinder 1 while the inner wall is a flexible element 2 of material such as rubber, which is sealed at the ends to the tube cylinder 1. The element 2 is pressed against the outer surface of the linings by means of air or other fluid under pressure introduced by way of a pipe 5. The carrier is suspended from a rod or by a hook-shaped arm 6. The liners are connected to a source of current by a connector 4a which may be connected to one or both of a pair of dummy end liners 4. Alternatively the connector 4a may be attached to a flexible conductor strip which is kept in contact with one or more liners 3 by the action of the flexible element 2. The connector 4a makes electric contact with a conductor rod 10 and the anode 8 is suspended by a connector rod 8a from a conductor 9. In a modification the element 2 is normally of an internal diameter smaller than the external diameter of the liners, to establish contact with the liners by its own resilience, but the element may be connected by a pipe 5 to a source of sub-atmospheric pressure to facilitate insertion or removal of the liners.

IPC: B24B3/48
Filed: 1926-10-05
Abstract: 288,348. Salerni, P. M. Oct. 5, 1926. Turning.- In a grinding-machine having a pair of oppositely movable grinding-wheels for grinding hollow-ground and other razor blades, &c., means are provided for advancing the grinding-wheels to compensate for reduction in diameter due to wear and dressing, and when the wheels are thus advanced, dressing-tools are advanced to a different extent so that the wheels are dressed in the advanced position. As applied to hollow-grinding razor blades, the machine consists of series of grinding-wheels 2 mounted on spindles 19 in supports 3 movable to compensate for wear by a screwed shaft 21. The dressing-tools, one for each wheel 2, are carried by arms 7 fixed to rods 6 reciprocable and angularly movable in the supports 3 and having pivotal connection to a bar 9 held against endwise movement by rollers 10. When the blocks are fed towards each other to advance the wheels 2, the rods 6 also move towards each other and the arms 7 carrying the dressing-tools move with these to a greater extent owing to the pivotal connections with the rod 9; the dressing-tools are then reciprocated by toothed sectors 31 and teeth 32 on the rods 6 to dress the wheels. The movements are derived from a rod 26, which is lifted by cam surfaces on a cam 24 through a roller 25, the rod carrying a pawl 28 engaging a ratchet wheel on a shaft 30 having thereon a worm 23 which drives a worm wheel 22 on the screw 21; the rod 26 also rocks a shaft 33 carrying the sectors 31. The dressing diamond 8 is carried by a screw entering a plug 60 adjustable on the arm 7 by a screw 63 and held in adjusted position by a screw 62. In a modification, for grinding the edge of a strip, the dressing-tools are carried by arms pivoted on the grinding-wheel supports and have bars thereon engaging between rollers mounted on fixed axes.

[Also in Division F2] A filling valve for a liquefied gas lighter comprises a stationary cylindrical member 2 extending into the fuel tank 1 of the lighter and having an exhaust opening 11 in its side wall, and a movable member 3 slidably sealed in the member 2 and having an axial fuel-filling passage 16 communicating with a radial passage 17 adapted to be closed by a sealing element 6 in the stationary member 2. The movable member 3 is urged to the closed position by a coil spring 8. The stationary member 2 has a bottom opening 10 below the sealing element 6. The spring 8 abuts a flange 13 of the movable member 3 which carries an annular seal 5 and from which extends a stem 14 with a pointed top 15 adapted to be connected to a filler container. Upon depressing the movable member 3, the seal 5 passes the exhaust opening 11 at the same time as, or after the radial passage 7 is clear of the annular seal 6. In a second embodiment, Fig. 3 (not shown), the annular seal 5 is mounted in a groove in the stationary member 2 and the flange of the movable member 3 is tapered and has extending from the lower edge, a cylindrical web which engages the annular seal. In a third embodiment, Fig. 4 (not shown), the stationary member 2 is internally shouldered to form a lower cavity containing the exhaust opening and of larger diameter than an upper cavity. The sealing element 5 is mounted on the movable member and engages the smaller diameter. In a further embodiment, Fig. 5 (not shown), the lower end of the movable member has a bulky cylindrical head which contains the radial fuel passage 17. In a final embodiment, Fig. 6 (not shown), the stationary member 2 has a horizontal partition through which the movable member passes with clearance and beneath which is an annular seal. An intermediate flange on the movable member 3 engages the annular seal, in the closed position of the valve.
